The AS_NRF51 FleX-BLE IC from American Semiconductor employs Nordic’s nRF51822 SoC to deliver a flexible connectivity solution for wearable, IoT, and logistics applications

Nordic Semiconductor today announces that Boise, ID-based American Semiconductor, has selected Nordic’s nRF51822 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) for its ‘AS_NRF51 FleX™-BLE’, a flexible integrated circuit (IC) that supports Bluetooth LE wireless connectivity in what American Semiconductor claims is the world’s thinnest and smallest Chip Scale Package (CSP).

The AS_NRF51 Flex-BLE is an ultra-thin version of Nordic’s nRF51822 SoC wafer-level CSP (WL-CSP), employing American Semiconductor’s ‘FleX™ Semiconductor-on-Polymer™’ (FleX SoP) process to reduce package size to approximately 35µm—roughly half the thickness of a human hair—while the addition of front- and back-side polymides from HD MicroSystems provides mechanical strength to allow the IC to bend without breaking. The result is an IC with a robust, thin, and physically flexible form factor designed for solutions that demand ultra thinness, physical flexibility, and high reliability in applications ranging from wearables and logistics, to the Internet of Things (IoT).

the availability of an established suite of support software and protocol stacks was essential – Richard Ellinger, American Semiconductor

Nordic’s nRF51822 SoC is ideally suited for Bluetooth LE and 2.4GHz ultra low power wireless applications. The nRF51822 is built around a 32-bit Arm® Cortex™ M0 CPU, 2.4GHz multiprotocol radio, and 256kB/128kB Flash and 32kB/16kB RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multi-link protocol stack. Nordic’s software architecture includes a clear separation between the RF protocol software and the application code, simplifying development and ensuring the SoftDevice doesn’t become corrupted when developing, compiling, testing, and verifying application code.

“We were looking for an advanced Bluetooth Low Energy solution that was rich in features and available in wafer format for conversion through our FleX SoP process,” says Richard Ellinger, VP Sales and Marketing, American Semiconductor. “The nRF51822 SoC’s Arm CPU, large Flash memory, low power consumption, and excellent 2.4 GHz radio performance made it the ideal choice.

“In addition, the availability of an established suite of support software and protocol stacks was essential, as we want our end customers to be able to quickly deploy ultra-thin, physically flexible Bluetooth LE systems into their markets. Many people are using the Nordic nRF51822 SoCs in their products today, and this will allow them to expand into new markets that may also require an ultra-thin, conformable, and/or physically flexible solution.”

Sub-6 GHz 5G Updates (5G NR)

Though there are high hopes for Millimeter-wave 5G solutions to solve all of our bandwidth woes, there will likely still be a couple, to several, years before large scale deployments of mm-Wave 5G occur. For the time being, wireless service providers are focusing on developing hardware and prototyping the new Sub-6 GHz 5G NR bands. These new bands cover 3300 MHz to 4200 MHz (n77), 3300 MHz to 3800 MHz (n78), and 4400 MHz to 5000 MHz (n79), and allow for up to 100 MHz of bandwidth. Due to varying regulation, each country has slightly different spectrum segments allowable for sub-6 GHz 5G NR. The most common frequency ranges are within 3400 MHz to 3800 MHz, and only a few countries currently have spectrum available beyond 3800 MHz. The US, for example, has two bands, a unlicensed/shared band from 3550 MHz to 3700 MHz and 3700 MHz to 4200 MHz available for sub-6 GHz 5G NR. Though not necessarily related, there have been efforts made in many countries to open up addition spectrum in the 600 MHz and 700 MHz frequencies for wireless telecommunications (TV white space spectrum), in the US this has emerged as two 35 MHz licensed spectrum segments and 14 MHz of unlicensed spectrum that may also be used in handsets and fixed wireless equipment alongside Sub-6 GHz 5G NR bands.

Several major modem chip suppliers have developed sub-6 GHz 5G NR modems, some even capable of facilitating the non-standalone mm-Wave 5G communications. As beamforming and beamsteering technologies aren’t needed for sub-6 GHz technology to overcome high RF path loss and atmospheric attenuation experienced by mm-Wave frequencies, the main focus for providing enhanced performance for sub-6 GHz 5G NR relies on massive MIMO and carrier aggregation technologies. These two capabilities require a large number of antenna elements with distinct RF pathways, and the ability for the RF front-ends (RFEs) and modems to operate, simultaneously, with several legacy and new 5G NR frequency bands. In order to implement multi-user MIMO (Mu-MIMO) and carrier aggregation, many modem chips are necessary along with a substantial amount of RF routing. Moreover, the use of such high-speed modems also leads to the use of high-speed digital interfaces that run at several Gbps. Though much of these new sub-6 GHz modem/radio/antennas would ideally be integrated, the sheer volume of RF/high-speed ports and pathways creates a substantial RF interconnect challenge during prototyping, testing, production, and even troubleshooting/maintenance.

Seven reasons why Bluetooth is perfect for the Industrial IoT

Seven reasons why Bluetooth is perfect for the Industrial IoT

Courtesy of u-blox : Seven reasons why Bluetooth is perfect for the Industrial IoT

Most of us use Bluetooth in some form every day, usually to link up things like our phones, smartwatches, headsets, mice and keyboards. In fact, Bluetooth has become so pervasive that the Special Interest Group (SIG) that oversees the standards, has predicted there will be an incredible 5.2 billion Bluetooth device shipments by 2022.

Amid all the excitement around Bluetooth in the consumer space, the fact that it’s also incredibly well‑suited for smart industrial use gets less attention. We wanted to shine a light on this, so have come up with seven reasons why those designing Industrial Internet of Things (IIoT) systems and networks should consider Bluetooth as their communications backbone.

1. It’s highly immune to interference
Bluetooth has clever ways of ensuring messages reach their destinations successfully, despite using the busy 2.4 GHz ISM frequency band (which it shares with the likes of Wi‑Fi and ZigBee, and others).

Adaptive frequency hopping helps ensure data successfully makes its way through the noise. Individual messages are broken into small data packets, which are sent over different channels in a pre‑defined sequence, known only to the transmitting and receiving devices. As many as 1600 channel‑switches can take place every second. Any data packets that don’t reach their destination correctly are re‑sent, and if the problem was caused by the channel, this gets flagged up so it can be avoided in the future.

2. You can operate lots of wireless devices in the same space
Several Bluetooth characteristics combine to ensure you can operate large numbers of devices in close proximity. Its short data packages – ideal for industrial measurement and control applications – only spend short periods on the airwaves. Equally importantly, Bluetooth’s automatic power control ensures data is broadcast at the strength required, so no shouting when there’s no noise. Both these factors help free up airwaves for other devices to use. Lastly – and essential when it comes to IIoT usage – Bluetooth is optimized to co‑exist with Wi‑Fi.

3. It can detect and rectify bit errors
In noisy environments, or where data is transmitted over longer distances (more on this below), there’s a chance of bit errors slipping into messages. Bluetooth can detect these, and take action to avoid unreliable channels, if they’re the cause.

It can also use what’s called ‘forward error correction’ (FEC) to rectify errors once data arrives at the receiver.

4. Bluetooth can integrate with your existing industrial systems
Serial ports are widely used in industrial applications. And thanks to its Serial Port Profile (SPP), Bluetooth can fit in with your existing designs. SPP emulates a full serial interface, complete with hardware handshaking via Bluetooth. Consequently, you can replace a serial cable with a wireless Bluetooth link, with either multi‑point or point‑to‑point operation.

5. The range is greater than you might think
Perhaps influenced by their experiences of Bluetooth in the consumer space, many people assume the technology only works at ranges up to a couple of meters. But Bluetooth can actually operate over much greater distances, even in harsh industrial conditions. And the latest‑gen Bluetooth 5 standard supports long‑range mode, which we’ve used to transmit messages up to 1.7 km. Mesh networks, where data is passed from node to node until it reaches its destination, can also help boost range, particularly in dense environments.

6. You can use it wherever you are
The Bluetooth standard is global, meaning you can use the same device anywhere on the planet – no need to source different components for industrial facilities in different markets. What’s more, because it’s so common in smartphones and other handheld devices, you can interact with Bluetooth‑enabled IIoT device using devices you probably already own.

7. Security is designed in
Three inherent characteristics of Bluetooth make it an extremely secure means of sharing data wirelessly. Firstly, the adaptive frequency hopping that we talked about earlier sees the transmitter send out data on a pseudo‑random sequence of channels. Only it and the receiver know which channels these are. So if someone was going to try to intercept the message, they’d need to listen on all channels, then attempt to piece together the right packets of data to form the full message.

Secondly, devices using Bluetooth 4.2 or later use a pairing mechanism that prevents in‑transit data from being intercepted in man‑in‑the‑middle attacks (LE Secure Connections).

And thirdly, Bluetooth devices can be set as ‘invisible’, meaning hackers won’t actually know they’re there. Connections are then only possible between devices that have been paired beforehand.

An incredible journey
The fact that Bluetooth is such an important part of the IoT is testament to the journey the technology has been on over the last 20 years. What was initially a means of syncing data between mobile phones, has continually evolved to meet new needs, including in the IIoT. And this is why many are now choosing it to underpin their next‑generation smart industrial facilities. Will you be joining them?
